Jason Calacanis is a recognized voice in Silicon Valley. Besides being a successful entrepreneur and host of the very popular "This Week in Startups," he's one of the world's most famous angel investors.

And in his new book, "Angel" (available July 16) he says Silicon Valley is the only place to be if you want to be a top founder or investor.

Now, Mr. Calacanis certainly knows his stuff when it comes to making successful investments in unheard-of tech companies. Most notably he invested $25,000 in Uber when it was only worth $5 million. This was back in 2010, when Uber was only operating in one city, and only had a couple of Lincoln Town Cars. Today it's worth around $70 billion in the private markets.

The timing of the death of Nancy Reagan just as Donald Trump's ascendancy to the Republican nomination seems increasingly unstoppable, is particularly painful for one Muslim lady in Brooklyn, Farhana, and her family.

That is because Farhana is not the name she goes by; she goes by Nancy—a nickname her family gave her in 1990, a year after she was born, and the year her family moved to the U.S. from Bangladesh. It's customary for Bengalis to give their children more English-sounding nicknames that family and friends will use throughout their lives.

A warning from Google to job seekers and recruiters: The résumé is dying. Through extensive trial, error and testing, the tech giant has found that the traditional way of attracting job seekers—post a job, screen résumés, interview, hire—isn't going to get you the best candidates.

That's because it reflects a misunderstanding of what makes a candidate successful in a job. It's not your work history or your grades. It's not how much industry experience you have. Nor it is whether you can solve brain teasers, or even show general cognitive ability, although that's very important.

Every entrepreneur has experienced what Ben Horowitz terms "the struggle." That's when things are going really, really badly. It's when, as he puts it in "The Hard Thing About Hard Things," "people ask you why you don't quit and you don't know the answer." But there always is a way, Mr. Horowitz believes, and it's the ability to spot the next move during the struggle that separates winners and losers.
